Case-Mix Adjustment of ECHO Survey Reports and Ratings

Principal Researcher: Laura Eselius, M.P.H.

Brief Project Description:

Experience of Care and Health Outcomes (ECHO) survey data will be used to develop a case-mix
adjustment model for the ECHO survey by examining the impact of individual characteristics on the
respondents’ reports and ratings of behavioral health care. Differences in plan type will be examined.
Additional analyses to be conducted include:

    1. What set of reporting measures is suggested by the factor structure of individual-level responses
       to the ECHO survey? Is the factor structure similar in subgroups of consumers defined by payer
       type (commercial versus Medicaid)? Is the factor structure similar in subgroups of consumers
       defined by reason for treatment (alcohol or drug use versus other behavioral health concerns)?
       How reliable are the proposed reporting measures for discriminating among health plans?

    2. Do plan ratings need to be adjusted for casemix differences before comparisons are made?

    3. Do subgroup differences in reports and ratings reflect differences in quality or differences in
       reporting tendencies?

Timeframe: Access to NCBD ECHO data was approved in January 2003 through June 2004. Extension
of access was approved in February 2004 through June 2005 to perform additional analyses.

Current Status:

This study is still in progress. Several papers will be submitted for publication following completion of a
dissertation in June 2004.

Analysis of Items within the CAHPS 2.0 Adult Core Survey to Inform Further Development of G-
CAHPS

Principal Researcher: San Keller, Ph.D.

Brief Description:

This research will include factor and regression analyses of CAHPS 2.0 Adult Core survey item data to
inform the development of a shorter Group CAHPS (G-CAHPS) survey. A qualitative comparison
(content analysis) of G-CAHPS and CAHPS 2.0 Adult Core surveys indicates that many of the G-CAHPS
items are similar or identical to the CAHPS 2.0 Core Survey items. Thus, analyses of the CAHPS 2.0
data could provide information of use to this project.

Timeframe: Access to NCBD 2002 Commercial adult data approved through 2004.

Current Status:

Findings have been used to inform development of Ambulatory CAHPS modules as part of the CAHPS II
research and development effort.

How Do Consumers Evaluate Their Providers? A New Paradigm with CAHPS Data

Principal Researcher: Koichiro Otani, Ph.D.

Brief Description:

The purpose of this study is to investigate the effect of patients’ reactions to three health care attributes (1.
getting care without long waits, 2. how well their doctors communicate, and 3. courtesy, respect, and
helpfulness of office staff) on their overall satisfaction with the quality of care and service (people’s
rating of their care). The first aim of the study is to determine whether patients simply average out their
reactions to multiple attributes mathematically (compensatory response) or whether their evaluation is
overly affected by either highly positive or highly negative healthcare attributes (noncompensatory
response). The second aim is to focus on the reactions to individual attributes in relation to overall patient
satisfaction. Given that an attribute is strongly related to overall patient satisfaction, is the relationship
linear or curvilinear? If it is curvilinear, does it display a diminishing marginal return function or an
increasing marginal return function?

Timeframe:

Access to NCBD 2002 and 2003 Commercial and Medicaid adult data approved through December 2004.

Current Status:

This project is still in progress.

Evaluation of the TRICARE Program: FY 2000―FY 2003 Reports to Congress

Principal Researcher: Peter Stoloff, PhD

Brief Description:

The TRICARE health care program evaluation use responses to the Survey of DoD Health Care
Beneficiaries to evaluate the changes in access to and quality of care which have taken place since the
inception of TRICARE. Since many of the questions in the DoD survey are based upon CAHPS items,
this project compares responses of those from the DoD population receiving their health care from
TRICARE with individuals represented in the NCBD database on common CAHPS items. The
comparison is limited to adult respondents.

Timeframe: Access to NCBD 1999-2002 Commercial adult and child data approved through February
2004.

Descriptive Results from Parents’ Experience of Health Care for Their Children

Principal Researcher: Joseph W. Thompson, MD, MPH

Brief Project Description:

This study will examine results obtained from surveys of parents about their experiences in achieving
health care for their children. These results will be obtained from available information from NCBD and
will constitute a convenience sample of submitted results for children in both Medicaid and commercial
populations. Three stages of analyses are anticipated (and are determined by (1) data availability; and (2)
dissemination opportunities):

           Stage 1: Descriptive summary of sponsor-specific and/or health plan-specific results.
           Stage II: Respondent-level analyses of parent-reported experiences in achieving health care
            for their children.
           Stage III: CAHPS 2.0 assessment of Medicaid and Commercial 1999 Results.

Timeframe:

Access to CAHPS 1.0 data approved from June 1999 through May 2000 for a 12-month period with
renewal requests for long-term trend analyses anticipated.

Current Status:

Selected study findings were presented at the 5 th National CAHPS User Group Meeting in October 1999.
Two abstracts have been accepted at the Pediatric Academic Societies Annual Meeting in April 2001,
with manuscripts to follow.

Analysis of Factors Influencing Variations in CAHPS Scores

Principal Researcher: Alan Zaslavsky, PhD

Brief Description: This project will include the following four analyses of CAHPS 2.0 survey data:

           Analysis of CAHPS 2.0 data for an employed population to determine a small set of
            dimensions describing the between-plan variation on the CAHPS report items.
           Analysis to determine how scale transformations or collapsing of categories might best be
            applied to improve between-plan discrimination.
           Analysis of amount of variation contributed by different geographic levels (region, MSA and
            plan) to plan-level CAHPS in a commercial data set.
           Analysis of relationships between CAHPS scores and plan characteristics (including tax
            status, national versus local ownership, size) and benefit design.

Timeframe: Access to CAHPS 2.0 data approved through April 2001.

Current Status:

Several papers on research findings have been drafted and are under review prior to submission for
publication.
